Figure 1 A comparison of the Swiss avalanche survival curve (bolded line) and the Canadian survival curve (dashed line) over the same 25-year period, from 1980 to 2015. Note the rapid drop after 10 minutes in the Canadian curve, although the curve maintains the same morphologic survival phases as the Swiss curve.3 Wilderness & Environmental Medicine 2017 28, 23-42DOI: (10.1016/j.wem.2016.10.004) Copyright © 2017 Terms and Conditions

Figure 3 The artificial air pocket device that diverts expired air away from inspired air during avalanche burial is intended to prolong survival of fully buried avalanche victims. The white arrows show the flow of inspired air, and the gray arrows show the flow of expired air.
